IMPROVEMENT IN RUFFL ERQ FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 131,012, dated September 3, 1872.

SPECIFICATION.

I, J OSEPH' W. LYON, of Chicago, in the county of (look and State of Illinois, have invented a new and useful invention in Pleaters for Sewing-Machines, of ,which the following is a specification:

The present invention relates to sewingmachine attachments intended for making pleats; and consists in a combination of parts, hereinafter more fully described, and provided with means for readily adjusting the stroke of the blade of the presser-foot so that it may have a longer or shorter movement for taking more or less cloth into a pleat, as particular work may require; and it may be considered an improvement on an attachment patented by me January 30, 1872. I

A represents a socket, constructed similarly to the one shown in the'patent referred to. This socket supports a pressure-foot, G, and a frame P, and the frame supports guides R P R, which support and guide a slide, J. To the said slide is rigidly fastened a metal arm,

. e, supporting the pleating-blade E, so that when the slide is moved back and forth by means hereinafter described the blade will also be moved and carry the cloth with it to form a pleat. The slide J is elongated at N so that a slot, K, may be made in itto receive a set-screw, L, Fig. 1, whose opposite end is shown at n, Fig. 3. This set-screw is clamped,

by means of the said part m, to the slotted part N K when the attachment is in use, the end n projecting through the slot in the vertical part M of the lever S, causing the latter,

when in motion, to move the slide J, and consequently-the blade. The lever S is pivoted tothe frame P at m, and to give the blade E a less longitudinal movement than it will have by the present position of set-screw L n the latter can be loosened and adjusted lower down in the slots of plate J and lever S.

Figure 1 is a perspective representation of the attachment, the blade E being on the left instead of the right hand. This position is better in many instances, as it saves folding a garment. Fig. 2 is an elevation of the slide removed from the other part; Fig. 3, a view of the inside of the lever attachment.

The loop (3 of. this lever is operated by the needle-bar I in the usual manner.
